LENG-SELVA GE MOTION.

SPECIFICATION forming part of Letters Patent N o. 691,204., datedJanuary 14, A1902.

Application ilerl August 20, 190I To all 'whom t zit/ty concern;

Be it known that I, HORACE H. SUTCLIFFE, a citizen of the United States,residing at Philadelphia, county of Philadelphia, and State ofPennsylvania, have invented a new and useful Improvement in Leno-SelvageMotions, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, which form a part ofthis specification.

My invention relates to an attachment for looms upon which more than onewidth of cloth is woven at the same time.

The object of the invention is to produce leno-selvages. l

My invention relates to that class oi' such attachments in which thethreads to form this selvage are passed through the eyes of the carriesthe frame for said needles the warpthreads upon the outside of the inneredges of the two pieces of cloth that are woven together pass. Theneedles are connected to a frame which is so supported as by appropriateconnections to be given a lateral movement in either direction, so as tolie on one or the other side of said warp-threads, and a verticalmovement to form a stitch with said warp-threads, the needles beingmoved alternately on each side of said warp-threads.

My invention consists in certain improvements which make the operationof said devices more certain and prevent the disarrangement of themechanism and enable the device to be of simple and cheap construction,all of which will be apparent from the embodiment of my inventionillustrated in the drawings and hereinafter described.

In the drawings, Figure l is a perspective view of the device inoperation. Fig. 2 is a side elevation of the device. Fig. 3 is a sectionon line 3 3 of Fig. 2. Fig. 4 is a plan view of the finished fabric.Fig. 5 is a partial side elevation of Fig. l. Fig. 6 is a perspectiveview of a modified form of embodiment of my invention. Fig. 7 is asection on line 7 7, Fig. 6.

A is a frame having the upper end a and the oriced lower end b. Betweenthese two ends extend the bars c, having grooves at o' on their innersurfaces, and the central rod or bar d, out of alineinent with the barsc.

. Serial No. 72.656. (No model.)

B B are needles, having the eyes Z22 b2 and the curved or bent tails b'ZJ. The needles are secured together, at a portion thereof between theeyes and th e tails of the needles, by the plate l). The width of theplate D is less than that of 'the orifice iu the end b of the frame A,so that said plate D, with. the needles B B', may readily slidevertically in said orificed end band move laterally slightly in eitherdirection. The curved tails Z9' b project beyond the end of frame A, sothat they are prevented from entering the oriiice. The needles above theplate are guided in their vertical and lateral movements by the groovec' on the inner surface of the bars c. The frame A is secured at theupper end to a fixed part F of the loom, as shown in Figs. l and 5. Thetails b b' of the needles B B have the oriiices e, from which cords E Elead to the jacquard or shafts of the loom. The threads F to form theselvagge-stitches are passed through the eyes b2 b2 of the needles B B'.The warp-threads H upon the outside of the inner edge of the two piecesof cloth that are woven together pass between the bars c. The cords F.E' are lifted alternately; but the alternation may be after each pick ofthe loom or after two or more picks. The lifting of the cordE will liftthe needles B -B and move the needles to the left, as shown in Fig. 2,while the movement of cord E will lift the needles and move the needlesto the right. In the construction speciiically illustrated I have shownthe cords E and E operated alternately at each pick, and the resultantweave formed is that shown in Fig. 4.

i The cord E or E is moved so as to tilt the needles B B', and then ast-he shed is formed the needles are lifted with the upper warpthreadsHand to one side orthe other of said threads. After the shuttle haspassed through the shed and the pick has been formed the tension uponthe cord E or E is released and by gravity the needles will descend tothe original position. On the next lift of the needles the opposite cordto that oi' the previous lift will be operated upon, resulting iubringing the needles to the side of the warp H opposite to that of theprevious lift, this resulting in the weave of Fig. 4.

In Figs.v6 and 7 I have shown a slightlymodified form of embodiment ofmy inven- IOO tion, in which the frame A is formed with a groove ororiice b4 from top to bottom and provided With slots M, through whichthe Warp-threads H pass. In this construction the free ends of theneedles are guided in their vertical and lateral movement by the wallsof the upper portion of frame A.

With my improved construction the device is of extreme simplicity. Theneedles are protected and guided in all their movements, and the deviceis thereby enabled to operate with certainty.

Having now fully described my invention, what I claim, and desire toprotect by Letters Patent, is-

l. The combination, with a grooved frame, of needles,a plate connectingsaid needles and of width less than the width of said groove, said plate`being adapted to move vertically and laterally in said grooved frame.

2. The combination,with a grooved frameL of needles, a plate connectingsaid needles and of width less than the Width of said groove, said platebeing adapted to move vertically and laterally in the grooved frame andguides adapted to directly limit and guide the free ends of said needlesin their lateral and vertical movement.

8. The combination, with a grooved frame, of needles, aplate connectingsaid needles and of Width less than the Width of said groove, said platebeing adapted to move vertically and laterally in the grooved frame andlguides adapted to directly limit and guide the free ends of said needlesin their lateral and vertical movement, the inner faces of said guidesbeing rounded.

4. The combination, with agrooved frame, of needles, aplate connectingsaid needles and of Width less than the width ot' said groove, saidplate being adapted to move vertically and laterally in the groovedframe, the tails of said needles being bent beyond the lower part of thesaid frame.

5. The combination, With a grooved frame, of needles, a plate connectingsaid needles and of Width less than the width of said groove, said platebeing adapted to move vertically and laterally in the grooved frame andguides adapted to limit and guide thefree ends of said needles intheirlateral and vertical movement, the tails of said needles being bentbeyond the lower part of the said frame.

6. The combination, With a grooved frame, of needles, a plate connectingsaid needles and of width less than the width of said groove, said platebeing adapted to move vertically and laterally in the grooved frame andguides A adapted to limit and guide the free ends of said needles intheir lateral and vertical movement, the inner faces of said guidesbeing` rounded, the tails of said needles being bent beyond the lowerpart of the said frame.

7. In a device of the character described, in combination with theneedles connected together at one end, and means to move said needlesvertically and laterally, of guides in line of movement of the verticaland lateral movement of and coacting with the free ends of the needles.

8. In a device ofthe character described, in combination with theneedles, connected together at one end, and means to move said needlesvertically and laterally, of guides in line of movement of the verticaland lateral movement of the free ends of said needles, the surface ofsaid guides coacting with said needles being rounded.

9. In a device of the character described in combination with a tubularframe, of needles movable vertically and laterally in said tubillarframe,the wall limiting the lateral movement of said needles and guidingthe needles in their vertical movement.

In testimony of which invention I have hereunto' set my hand, atPhiladelphia, on this 7th day of August, 1901.
